We theoretically and numerically investigate the transport of active colloids to target regions,
delimited by asymmetric energy barriers. We show that it is possible to introduce a …

Transport in the realm of soft matter is strongly influenced by diffusion. Conditions far from
thermal equilibrium and non-linear dynamics may give rise to unexpected transport …

Spontaneous persistent motions driven by active processes play a central role in
maintaining living cells far from equilibrium. In the majority of research studies, the steady …

Diffusive transport of particles or, more generally, small objects, is a ubiquitous feature of
physical and chemical reaction systems. In configurations containing confining walls or …

A tilted two-layer colloidal system is constructed for the study of force-assisted barrier-
crossing dynamics over a periodic potential. The periodic potential is provided by the bottom …

Transition paths are rare events occurring when a system, thanks to the effect of fluctuations,
crosses successfully from one stable state to another by surmounting an energy barrier …

The transport properties of colloidal particles in active liquids have been studied extensively.
It has led to a deeper understanding of the interactions between passive and active …

We consider the Brownian motion of a colloidal particle in a symmetric, periodic potential,
whose potential barriers are subjected to temporal oscillations. Experimentally, the potential …

Modeling the couplings between active particles often neglects the possible many-body
effects that control the propulsion mechanism. Accounting for such effects requires the …

We study the dynamics of a tracer in a dense mixture of particles connected to different
thermostats. Starting from the overdamped Langevin equations that describe the evolution of …
